Screen

Overview

Display text, controlled by a Graphics Card in a Case.

• Maximum resolution: 50x16/80x25/160x50.
• Maximum color depth: 1/4/8.

Screens allow computers to display text, by binding them on a graphics card and then changing their text buffer. Think of these screens more like... chalk boards. You don't have to send the data to display each "frame", instead you set something to display, and the screen will continue displaying it until it's told to display something else. There are a few scenarios where a screen's buffer will be cleared, though: when they are merged into a multi-block screen, when the controlling computer is turned off, and when they are bound by a graphics card.

Note that screens of all tiers can be controlled by graphics cards of all tiers. However, the minimum capabilities of each combination apply. For example, when using an advanced screen via a basic graphics card, the maximum resolution and color depth will be limited by that of the graphics card.

Tier two and three screens allow mouse input: it generates a touch signal on all computers in its network whenever a user either right-clicks/activates the display area of a screen without a keyboard - like a giant touch screen - or when left clicking on the display area in the GUI of a screen with a keyboard. They also generate a walk signal when a mob moves while walking on the screen.

As of version 1.3, tier 2 screens use a 16 color palette, that defaults to the Minecraft colors and can be manipulated as desired. Tier 3 screens have a hybrid color system, where 240 colors are "automatic" and a 16 color palette exists that defaults to different shades of grey, but can also be manipulated as desired.

The Tier 1 Screen is crafted using the following recipe:

• 4 x Iron Ingot
• 1 x Glass
• 1 x Microchip (Tier 1)
• 3 x Redstone Dust

The Tier 2 Screen is crafted using the following recipe:

• 1 x Microchip (Tier 2)
• 1 x Rose Red
• 1 x Cactus Green
• 1 x Lapis Lazuli
• 4 x Gold Ingot
• 1 x Glass

The Tier 3 Screen is crafted using the following recipe:

• 1 x Microchip (Tier 3)
• 4 x Obsidian
• 1 x Glass
• 3 x Glowstone Dust

Component API

Component name: screen. Callbacks:

isOn

isOn():boolean

Returns whether the screen is currently on.

turnOn

turnOn():boolean, boolean

Turns the screen on. Returns whether it was off and the new power state.

turnOff

turnOff():boolean, boolean

Turns off the screen. Returns whether it was on and the new power state.

hardwareResolution

hardwareResolution(): number, number

Gets the maximum resolution supported by the screen regardless of an attached GPU.

hardwareDepth

hardwareDepth(): number

Gets the maximum color depth supported by the screen regardless of an attached GPU.

getAspectRatio

getAspectRatio():number, number

The aspect ratio of the screen. For multi-block screens this is the number of blocks, horizontal and vertical.

getKeyboards

getKeyboards():table

The list of keyboards attached to the screen.

setPrecise

setPrecise(enabled:boolean):boolean

Set whether to use high-precision mode (sub-pixel mouse event position). Requires Tier 3+ Screen.

isPrecise

isPrecise():boolean

Check whether high-precision mode is enabled (sub-pixel mouse event position). Requires Screen (Tier 3).

setTouchModeInverted

setTouchModeInverted(enabled:boolean):boolean

Sets Inverted Touch mode (Sneak-activate opens GUI if set to true).

isTouchModeInverted

isTouchModeInverted():boolean

Check to see if Inverted Touch mode is enabled (Sneak-activate opens GUI is set to true).
